With the rapid urbanization of Beijing in recent decades, comprehensively understanding its regions' structures and functions becomes more and more challenging, though it indeed plays a fundamental role in the city planning. While fortunately, the accumulation of huge mobility records from massive individuals provides an unprecedented big-data window for solving this issue. In this paper, we segment...
Although it is believed that many animals tend to move together as group motion has greater benefit, until now we know only a little on how individuals interact with their neighbors. In this study, we build a directed social network for large herbivores motion based on a complex network analysis framework. By calculating the basic statistics of the two networks (for two interacting species), such...
Peer-to-peer file sharing systems, most notably Bit-Torrent (BT), have achieved tremendous success among Internet users. Recent studies suggest that the long-term relationships among BT peers can be explored to enhance the downloading performance; for example, the cooperation of peers to re-share old contents. However, whether such relationships can be built still remain unknown. In this paper, we...
The web service technologies enable us to develop the web community to provide corresponding services for users. In this paper, we proposes a new structure of distributed mobile society, and explicit it from three architectural cornerstone: naming, routing and transport. The INS naming and routing mechanism enables users to manage and access nodes in the network easily and effectively. The structured...
The hot commercial community networks wipe the Internet, and the prospect of mobile Internet attracts the Internet community services into the mobile filed. And the availability of user-location information is facilitating the development of new personalized, location-based applications. However, as of today, most of these applications have its protocols and cannot intercommunicate, makes it inconvenient...
The distributed architecture of vitual community based on P2P has proved to resolves some problems from central architecture such as single point failure. In this paper, drawing on the idea of SOA, we propose an optimized architecture of distributed mobile P2P community system, in which the virtual communities are divided into separately service components which can be deployed in the overlay networks...
